This is our recommended follow-up labs 8-12 weeks after starting a TRT protocol or after a change in dosage. This checks your target total testosterone serum levels, essential hematology markers and blood viscosity markers, as well as rate of aromatization via estradiol. After order completion, a provider will submit your Lab Requisition Form to Labcorp, within 24 (business) hours. You will also be emailed a copy of your LRF to take to your nearest Labcorp with valid photo ID. Your results will be available in your Labcorp Patient Portal as soon as they become available.

Although fasting is not required for this lab, please ensure adequate hydration. It is typically advised for males to pull at trough (lowest) levels, but it is recommended females pull at peak (highest) serum levels. For your own records, make note of your last injection/administration time.
